Description
技术领域technical field
本实用新型涉及电动汽车车身产品领域，尤其涉及一种电动汽车轻量化前防撞横梁总成及前防撞安装结构。The utility model relates to the field of electric vehicle body products, in particular to a lightweight front anti-collision beam assembly and a front anti-collision installation structure of an electric vehicle.

目前，在国家政策的调控下，电动汽车得到了飞速的发展，电动汽车作为新能源汽车的代表，具备经济、节能、环保等优点。但也有缺点，比如续航里程的问题，由于受到前后悬架、座椅横梁、内饰件等限制，导致电池的布置空间有限，而目前电池的体积相对比较大，所以在一定程度上很难通过增加电池的数量来提高续航里程。所以尽可能在车身上进行轻量化设计才能提高续航里程。以前，防撞横梁总成以抗弯性能、轻量化、行人保护为出发点，以CAE等参数化技术为手段，对标钢材、铝合金材料为基础，提出前防撞横梁总成从材料、工艺及截面形状改进方案，达到改善电动汽车碰撞安全性能及提升续航里程。而电动汽车车身必须符合很多的要求，首先不能影响车身性能，其次要保证汽车碰撞的时候乘客受到的伤害最低。车身轻量化目前只能从材料、结构上进行设计，所以需要一种更为合理的轻量化的前防撞横梁总成。At present, under the control of national policies, electric vehicles have developed rapidly. As a representative of new energy vehicles, electric vehicles have the advantages of economy, energy saving, and environmental protection. However, there are also disadvantages, such as the cruising range. Due to the limitations of the front and rear suspensions, seat beams, and interior parts, the battery layout space is limited, and the current battery volume is relatively large, so it is difficult to pass the battery to a certain extent. Increase the number of batteries to increase the cruising range. Therefore, the lightweight design of the body as much as possible can improve the cruising range. In the past, the anti-collision beam assembly was based on bending resistance, light weight, and pedestrian protection. Using CAE and other parametric technologies as a means, and based on benchmarking steel and aluminum alloy materials, it was proposed that the front anti-collision beam assembly should be based on materials and processes. And the section shape improvement scheme, to improve the collision safety performance of electric vehicles and increase the cruising range. The body of an electric vehicle must meet many requirements, first of all, it must not affect the performance of the body, and second, it must ensure that the passengers suffer the least damage when the car collides. At present, the lightweight of the body can only be designed in terms of materials and structures, so a more reasonable and lightweight front anti-collision beam assembly is needed.
